Gas purge micro solvent extraction: A rapid and powerful tool for essential oil chromatographic fingerprints

This work aimed to extract perfume from the leaves of Cymbopogon citratus using three extraction methods viz: distillation, solvent extraction and expression or effleurage. About 150 g of dried lemons grass were extracted using ethanol as the solvent to obtain essential oils required for the formulation of perfumes. The result of the hydrodistillation process showed that 1.23 g of essential oil per 130g of dry lemongrass produce 0.95% oil at 78 °C, while the effleurage method was 2.55 g of essential oil per 130 g of dry lemongrass sample thereby producing 1.96% oil yield. The solvent extraction method gave 2.7 g of essential oil per 130 g of dry lemongrass sample. This gives about 2.08 % yield of essential oil at a temperature of 78°C i.e. the boiling point of ethanol. The solvent extraction method yielded 2.08%, the effleuragemethod yielded 1.96% and the hydrodistillation method yielded 0.95% essential oil respectively. In conclusion, solvent extraction gave the highest yield because of less exposure to air and heat, which is highly recommended as the most suitable method for the extraction of essential oil.

Odorous Substances

The production of essential oil from tobacco leaves for insect repellents using a combination of solvent extraction was investigated. Tobacco essential oil is generally different from other essential oils, which usually consist of several special aroma compounds. The tobacco essential oil and solvent extracts were analyzed by gas chromatography with a mass spectrometer (GC–MS). Tobacco essential oils are concentrated odorous substances. Nicotine is present as a major substance and found only trace amounts of the essential oils. Nicotine is an insecticide that affects to insects. This research showed that a development of products forms tobacco leaves and environmentally. This product evaporated pass through a packaging made from luffa gourd. The luffa gourd is a natural packaging can be easily degradation in the environment. Moreover, this product also helped to reduce the hazardous chemicals or pesticides usage in agricultural activities and not residues in the environment for long times.
